I was surprised when Sara realized she didn’t need a bank to lend money.

Sara and Maria were sitting beside a quiet lake, watching the water move between the trees.

Sara suddenly looked at her phone.

“If I want to lend my money, who has to approve it?”

Maria smiled.

“A bank, usually.”

Sara nodded.

“Then how can people lend or borrow money without one?”

Maria looked at her.

The two girls went silent.

For a moment, they only heard the birds and the sound of the water.

Then Maria smiled.

“Through a smart contract.”

Sara looked surprised.

“No bank?”

“No traditional intermediary.”

The idea is simple:

Instead of asking a bank to manage the loan, a smart contract can hold assets, follow predefined rules, and execute transactions automatically.

That is one of the ideas behind DeFi — decentralized finance.

It doesn’t mean there are no risks or rules.

It means some financial functions can be built directly into blockchain-based systems.

Sara looked back at the lake.

“So the question isn’t only whether we can remove the bank…”

“It’s whether code can safely handle the job.”

And suddenly, the lake felt very quiet again.

What financial service would you trust a smart contract to handle?
